Electric cars are pretty cool, even if they aren’t quite mainstream yet. Real-life Tony Stark fellow Elon Musk has been doing some impressive work at Tesla over the past few years, trying to make the perfect electric car. He recently tweeted out another one of his ideas that they’ve been working on: an automatic charging cable that’ll come “out from the wall & connects like a solid metal snake. For realz.” Holy crap, that sounds terrifying and awesome at the same time. I imagine it’s based off of those cool robotic snakes. Automation taking care of everything is a little frightening, but pretty impressive, too!
